Application Case Study (Pulp/Paper Operations) The pulp and paper industry has traditionally been a consumer of large amounts of fresh water and power. Recently, increased focus has been given to the optimized efficiency of paper mills and to the environmental sustainability footprint of the industry. Therefore, water resource management has become a more critical factor ...

A large number of food processors utilize ponds to treat their wastewater. Most of the time these ponds are aerobic in which they use oxygen to degrade the wastewater biological oxygen demand (BOD). Fruit and vegetables contain a high amount of simple sugars and other organic compounds that when exposed to water are released into the water stream. These organic compounds require oxygen to degrade ...

The Quaker Oats plant in Peterborough, Ontario, Canada produces some seven million cases of Harvest Crunch® cereal and cake mixes annually. In the process, residue from the conveyors, dryers and other processing equipment ends up on the floor. Periodic equipment washdowns add water to the solid and liquid residue, which contains edible fats, starches and sugars. During house-cleaning operations, ...

To prevent eutrophication in receiving waters, many astewater treatment plants are being firected by regulatory agencies to achieve very low levels of total nitrogen (3-4 mg/L TN or lower) in the effluent. Dissolved organic nitrogen (DON) component is included within these total nitrogen limits. The regulations assume that DON is completely biodegradable, and therefore needs to be included in any ...

DEVISE ENGINEERING S.A. has designed, engineered and is currently producing a new series of State of the Art Portable Sewage Treatment Plants (PSTP), incorporating advanced Ultra-Filtration (MBR) technology. These Plants are used for multiple “emergency” & “short-term” purposes with the ability to re-use the treated effluent. The particular Portable STP can be easily ...

Whether you own, operate, or help manage a municipal or industrial facility that deals with wastewater, it’s important to understand how wastewater treatment can play a significant role in the overall health of your business, especially when it comes to meeting effluent regulations. This is an important part of the wastewater treatment process to consider, as ignoring it could earn your ...

Patented Bioreactor uses Q-PAC Randomly Packed Media in Application of Specific Bacterial Cultures for Treating High Strength Industrial Waste for BOD and Odor Reduction in a Cheese Manufacturing Plant A cheese manufacturer in Upstate New York with one three million gallon lagoon is testing a bioreactor (TVTBIO 32) from TVT US Corporation. The concept is essentially the same as bacteria eating ...

The Detroit WWTP had experienced intermittent high BOD in the dechlorinated final plant effluent from September 2003 to October 2004 and was not related to wet weather events. No NPDES violations occurred. A short-term cost effective laboratory investigation was initiated during the months that the intermittent high BOD values were occurring to determine possible causes. The results of the ...

Challenge A fish meat processing plant wanted to reduce their effluent discharge costs and eliminate chemical cost in primary waste water treatment. Solution Genesis Water Technologies with its local partner provided engineering, and design of a electrocoagulation solution with prescreen and post solids separation that eliminated chemical usage in the primary ...

In the late 1960s, the mounting public pressure in the developing countries for control of pollution stimulated investment in a host of special studies to find the best alternative ways of protecting the aquatic environment. One of the most important parameters for knowing the water quality is Dissolved Oxygen (DO) because various other parameters are interrelated with it and changes accordingly ...

Ask the expert: What are the differences between Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD)? Answer: Both COD and BOD test methods aim to give an indication of the amount of pollution in a water sample. COD is the amount of oxygen required to chemically breakdown the pollutants whereas BOD is the amount of oxygen ...

The dual objectives of this study are to: (1) examine the relationship between COD and BOD in seawater environment with a rapid but reliable method for the measurement of BOD in seawater, and (2) establish the relationship model between BOD5 and COD in the firth of Dongbao River to predict the values of BOD5. The first objective is met by the successful development of a technique utilizing ...

With the steady increase in poultry processing rates there has been a corresponding increase in wastewater pollutant concentrations. Despite mechanical improvements in wastewater treatment, many poultry processors continue to pay unnecessarily high fees for municipal water discharges. $100-million-annual processor, Michigan Turkey Producers, in conjunction with Lyco Manufacturing, has set up a ...

The patented EOH2O electrolytic oxidation process has been employed as a continuous batch treatment system for reduction of nutrients, TSS, odor, and pathogens in manure lagoons for several years. Due to the positive results of such applications, several Pacific Coast rural municipalities approached Aquatic Technologies to determine if a constant flow-through treatment system could be designed to ...

ABSTRACTThe bottled water industry uses a machine specifically designed for the washing of its containers (19-L capacity) and generates 6-L wastewater/container. This effluent can be used for watering of green areas and car washing. The objectives of the present work were to characterize the effluent and to propose a specific treatment to enable reuse of the effluent from the container washing ...

Ozone has been used for many years to treat pathogens such as bacteria and algae in water for applications such as drinking water supplies and air conditioning system cooling water. More recently, most water bottlers have adopted ozone. Ozonated water for treatment of fruit, vegetables, fish, etc. in the U.S. awaited the GRAS approval. Now that has happened, and projects are emerging everywhere. ...

It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...

Clean drinking water is an essential need of mankind. Often surface water like rivers or lakes is used as drinking water source. To prevent these resources from pollution the effective treatment of waste water is a must. For example in China 75% of discharged waste water is coming from pulp and paper, textile and dyeing industries. To run a waste water treatment plant in the most efficient way ...

An industrial waste treatment system in Texas used AQUACLEAN / ACF-32 in their plant to reduce BOD, Ammonia, TOC, and TSS. This industrial site was processing water-soluble polymers that were proving to be difficult for their activated sludge system. In the existing system design, the influent stream is first treated by a pH adjustment to a level of 12 or higher, and then is later anaerobically ...
